Geologically speaking, the Taipei Basin was a lake until 200,000 years ago. Historically, soil and boulders from 3 steep rivers had been transported into the lake forming the present basin. The underground conditions of the existing basin, is soft or sandy soils and includes many boulders.

To cope with Taipei's rapid development as a business and financial center in the region, the city authority has expedited effective use of under-ground facilities for public transportation, sewage/water supply systems, and conduit for power, gas and telecommunications.

Daiho's 8 sets of iron-mole or TBM are currently in full operation and transforming Taipei's underground while overcoming adverse geological conditions such as soft or sandy strata with boulders, also while protecting existing underground structures. At Section CK570H pictured below, two pairs of iron-moles are driving through a complex twisting alignment just under a congested area of Taipei which features housing and school buildings among other existing above ground constructed facilities
